CARD FOR LOOSE-LEAF-INDEX DEVICES.
- Application filed December 30, 1911.
To all whom it may concern:
Be it known that I, GARRETT II. HUISING, a citizen of the United States, residing in Chicago, county of Cook, and State of Illinois, have invented a certain new and useful Improvement in Cards for LooseIieaf-Index Devices, of which the following is a specification.
My invention relates to that class of card indexes in whicha card or group of cards is displacedfrom the normal plane of the remainder by any suitable mechanism. Numerous devices of this kind have been invented, but all with which I am familiar are inoperative due to the fact that the friction existing between the surfaces of the cards is so great that when the mechanism is operated for the purpose of elevating a single card, it will carry up not only that card but always the cards adjacent to it, while in many instances as many as a dozen cards are carried up by the elevation of a single card. This is due not only to the friction existing between the surfaces of the cards, but is frequently caused by the engagement of the pin or clip which forms the connection between the card and the elevating mechanism engaging the next adjacent card.
In most card indexes of this character it is deemed necessary to provide a resting place for the cards, so as to prevent their resting upon the pins themselves. This is generally done by having a shoulder near the bottom of the side walls of the box upon which the cards mayrest. Practice has shown, however, that in a comparatively short time the constant replacing of the cards breaks the edges or corners of them down to such an extent that they will slip off of the shoulder thus formed and become wedged so that when the user desires to elevate the card, which had wedged itself in this way, he finds it impossible to do so.
My invention has for its object to provide means for overcoming all of these objections and produce a card having protectors secured to its ends, which will, insure the rise of a single card Without reference to the number of cards which are in the box.
My means of accomplishingthe foregoing maybe more readily understood by having reference to the accompanying drawings, which are hereunto annexed and are a part of this specification, in which:

mentary portion of a card index box, employing cards provided with my improvement. Fig. 2 is a side elevation of the same, a portion of the outer wall being broken away to show the interior construction. Fig. 3 is an enlarged detail view of the top of one of the cards. Fig. i is a front view of the same. Fig. 5 is an enlarged perspective view of one of the protectors.
Similar reference numerals refer to similar parts throughout the entire description.
As shown in the drawings, 1 is the box which is provided with a plurality of cards 2, the corners of which rest upon shoulders 3 and 4 formed near the bottom of the side walls 5 and 6. A plurality of longitudinally movable bars 7 are located in the bottom of the box being connected by means of toggles 8 to rising bars 10. The front end of each of the longitudinally movable bars extends upwardly and is secured to a rod 11, which is slidably mounted in the front wall of the box, the outer end of the rod being provided with a key or indicator button 12, upon which may be marked or engraved the desired numeral, letter or character. A. plurality of pins or clips 18 which connect the rising bars or card displacers to the cards are secured to the latter in positions which will register with the desired rising bars 10.
My protectors 14: are shown on the ends of the cards 2 as clearly seen in Figs. 3 and 4 andcomprise a fold of tin or other material, which will furnish a satisfactory bearing surface. The protectors 14 are secured to the ends of the cards, and the tin of which they are formed being of the same thickness as the pins 13, effectually precludes their engaging the adjacent cards in any manner whatever. They also serve to space the cards apart so that there is ,no contact between adjacent surfaces, the only contact be- .ing at the edges where the metal strip en- This construction also insures the corners of the cards being worn in use,
and as a result of such wear dropping off of the shoulders, which form their resting place,.and in this manner rendering thedevice inoperative.
Although I have described the reinforcement as being formed of tin, I do not wish to limit myself to that material, as other substitutes may be found in practice, which serve equally well, the essential feature being that the material used shall .be sufliciently thick to clear the pins on adjacent cards, and which furnish a satisfactory index, provided with mechanism adapted to elevate a predetermined card or group of cards above their normal position, and comprising connectors seeu ed to the bottom of the cards and adjustable longitudinally thereof, of a plurality of loose leaf cards,-
the ends of which are providedwith a metal binding, the length of which corresponds to the height of the card, said binding being formed of material which forms a suitable bearing surface uponwhich the next adjacent protector slides when being elevated.
2. The combination with a casing and a plurality of bars therein adapted to elevate a card or group of cards above their normal-position, of a plurality of cards each having a binding 'of metal secured to the ends, and concealed connectors detachably secured to the lower edges of said cards and Y I adjustable longitudinally thereof.
3. The combination with' a easing having mechanism for elevatlng'a s ngle card or group of cardsabove their normal positlon and a plurality of loose leaf oards, of proformed of material which is stifi'er than the cards and adapted to form bearing surfaces on the sides thereof, a plurality of pins detachably secured to said cards, which engage the elevating mechanism.
5. The combination with a casing having mechanism for elevating a single card or group of cards above their normal position ,and a plurality of loose leaf cards, a plurality' of pins which engage the elevating mechanism detachably secured to the lower edge ofthe cards, protectors on the ends of said cards Whereby'they are spaced apart, said protectors being formed of material which forms a suitable bearing surface upon which the cardsslide when being elevated. In testimony whereof I have signed the foregoing specification.
